The following specifications shall be satisfied when the capacitors are restored to
25C after
subjecting them to DC voltage for 2,000 hours at
85C with the rated ripple current applied.
The sum of the DC voltage and peak AC voltage must not exceed the full rated voltage of
the capacitors.
Capacitance change: ≤ 20% from initial measurement
ESR change : ≤ 300% of initial specified limit
Leakage current : ≤ initial specified limit
Shelf Life The following specifications shall be satisfied when the capacitors are restored to
25C after
exposing them for 500 hours at
85C without voltage applied. The rated voltage shall be
applied to the capacitors for a minimum of 30 minutes, at least 24 hours and not more than
48 hours before the measurements.
Capacitance change: ≤ 20% from initial measurement
ESR change : ≤ 300% of initial specified limit
Leakage current : ≤ initial specified limit
Characteristics
